Intermap Technologies Inc.20151210ORI_n5945w16115P_sup1.tif1Raster Digital DataOrthorectified Radar ImageCore Product Version: 4.4.1, Edit Rule Version: 3.5Englewood, COIntermap Technologies Inc.Intermap ORI product is a raster imagery product with terrain information captured at a 0.625-meter resolution. It is generated using Intermap's STAR technology (Interferometric Synthetic Aperture Radar), which is mounted to an aircraft. The ORI data files are digital representations of the radar response signal and is spatially coincident with the DSM and DTM data. These ORI products represent the first reflective surface as illuminated by the radar. Accuracy statements are based on areas of moderate terrain. Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. The ORI is stored as a contiguous dataset spanning continental land masses where we have captured data. It is available in specific areas of interest or in 15-minute by 15-minute tile areas. For more detailed information, refer to Intermap's Product Handbook at http://www.intermap.com/Portals/0/doc/Brochures/INTERMAP_Product_Handbook.pdf.The ORI imagery is used for visual representation and for applications such as feature classification and spatially referencing aerial and satellite imagery.2015071620150728The above dates refer to the time of field data acquisition and therefore reflect ground conditions at that time.CompleteOngoing-161.311453-160.94081960.01669659.733196MEL_Scientific-Engineering_Field_ThesaurusElevationCartographyGeodesyGeographyHypsographyMappingPhotogrammetryStereophotogrammetryTopographyRadarInterferometricRemoteSensingSARDEMDTMDSMORIINSARIFSARIFSAREGEOSARheightNoneAlaskaUSAMEL_Environmental_Domain_ThesaurusTerrainEarthSurfaceGroundFirst2015JulyPurchaseEnd User License AgreementIntermap Technologies Inc.Data Archive Managermailing address8310 South Valley Highway, Suite 400EnglewoodCO80112-5847USA(303) 708-0955(303) 708-0952service@intermap.comThis data was produced by Intermap Technologies Inc.This data is delivered on interoperable media with metadata. The data set was developed on a Microsoft Windows system using Intermap's propriatory Interferometric Editing System (IES).Calculation of the digital elevation model is described in the Intermap Technologies Core Product Handbook User's Guide. http://www.intermap.com/Portals/0/doc/Brochures/INTERMAP_Product_Handbook.pdfNoneNoneAll data products are 2 meters RMSE or better in areas of unobstructed flat ground.NoneThe NEXTMap ORI products are derived using Intermap Technologies' STAR-3 airborne Interferometric SAR data acquisition system. The data for this tile was captured at 25200 feet above mean sea level with a primary look direction of West and the swaths with IDs 9, 21, 22, 32, 86, 87, 88 and 92. ORI products represent what is captured by the radar. Most incidents of missing data are due to radar shadow and layover in high-relief areas such as mountainous regions and highly developed urban areas and correspond to the look direction of the radar. Areas where null data occurs within an image, such as shadows, are assigned the value 0. Areas where the sensor could not resolve the return signal are assigned the value 1.20151028RasterPixel4799228112Albers Conical Equal Area55.065.0-154.050.00.00.0coordinate pair0.6250.625metersNAD83 CORS96 EPOCH 2003.00GRS806378137.0298.2572221018 bit GeoTIFFThe ORI is an 8 bit georeferenced TIFF image on a 15-minute by 15-minute (lat/long) grid.
